From 5e6e9852d6f76e01b2e6803c74258afa5b432bc5 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 3 Sep 2020 16:22:35 +0200 Subject: uaccess: add infrastructure for kernel builds with set_fs() Add a CONFIG_SET_FS option that is selected by architecturess that implement set_fs, which is all of them initially.
